IPC: H04N9/79
Filed: 1986-08-28
Abstract: PURPOSE:To simplify a circuit constitution by providing an inserting means for inserting the burst signal of a chrominance sub-carrier into a television signal at a transmission side and a control means for controlling the operation of the recording means of the television signal at a receiving side in response to the presence and the absence of the burst signal in the receiving side. CONSTITUTION:When a switch 4 is turned on, the 3.58 MHz burst signal is inserted into an NTSC television signal. Only the 3.58 MHz burst signal is separated based on a gate pulse signal GP inputted from a synchronizing separation circuit 25 among the chrominance sub-carrier signals inputted to a burst separation circuit 30 and the burst signal is outputted to a color killer detection circuit 35. The burst signal is mixed with the sine wave signal of 3.58 MHz outputted from a 3.58 oscillator 36 and detected and outputted to a color killer circuit 37. The color killer circuit 37, when the detecting output is inputted, outputs the control signal of H level to the control input terminal of a switch 31 and to the (a) side of a switch 38.

Abstract: PROBLEM TO BE SOLVED: To enhance the performance of a MOS-FET, by forming a high- impurity concentration region of a conductivity type reverse to a shallow diffusion layer formed in the peripheral region of a gate electrode under this shallow diffusion layer selectively, and preventing a high impurity concentration distribution from exerting an influence on other regions. SOLUTION: In a silicon substrate 2 for a gate sidewall spacer composed of a silicon nitride film 22 formed on the side of a gate electrode 10, a shallow diffusion layer 16 is formed, and besides a high-impurity concentration region 18 of a conductivity type reverse to the diffusion layer 16 is formed under this. In an element isolation region 4, a shallow diffusion layer 16 and a high- impurity concentration region 18, a deep diffusion layer 24 of the same conductivity type as the shallow diffusion layer 16 is formed. Accordingly, it becomes possible to reduce a junction capacity generated in the junction between the high-impurity concentration region 18 and the deep diffusion layer 24, since the high-impurity concentration region 18 is formed so as not to lap over at least the whole region of the deep diffusion layer 24.
